The short explanation
It can be part of the reason. When blood sugar is high, sugar spills into the urine, which helps bacteria grow. Diabetes can also reduce the body's ability to fight infection and, over time, can affect the nerves that control how well the bladder empties. All of this makes urine infections more frequent and sometimes more serious in women with diabetes. Better sugar control often reduces infections, but it is also worth checking for other causes when infections repeat.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Some diabetes medicines work by passing extra sugar into the urine, which can increase genital thrush and urine infections in some women. Do not stop any medicine yourself; discuss it with your doctor.
- With repeated infections, doctors usually send a urine culture each time, check your recent HbA1c, and may order an ultrasound to look at the kidneys and how well the bladder empties. Menopause, constipation and sexual activity can also play a part.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell why your infections keep returning. Your doctor will look at your sugar control, cultures and possibly a scan to understand the pattern.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is my sugar control contributing to these infections?
- Could any of my diabetes medicines be making infections more likely?
- Should each infection be confirmed with a urine culture?
- Do I need a scan to check my kidneys and bladder emptying?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Get help the same day
- Get care the same day if you have fever, back pain, vomiting, or sugar readings much higher than usual with an infection.
Book an appointment soon
- See a clinician within a few days when urine symptoms start, so a sample can be tested before treatment.
Raise it at a routine appointment
- Book a routine review of your diabetes and infection pattern with your doctor.
